Toallwhomitma/yeoncem:

Be it known that we, WAIIIER J. WAR- NER and DANIEL A. LIoH'rY, citizens of the United States, and residents of St. Louis, Missouri, have invented certain new and useful Improvements in Instantaneous Water- Heaters, of which the following is-a specification. I

Our invention relates to an improvement in instantaneous water heaters, and .has for its object to provide a heater shell in which live steam and water are brought in direct contact and the water discharged in a heated condition.

A further object of our invention is to provide a heater shell having a plurality of compartments mounted upon a base provided with'aplurality of ports, each com-j inunicating with a designated compartment of the heater shell wherein waten and steam are admitted and brought in direct'contact durin the circulation, and discharged in a heated condition. I

In the drawingsFigure 1 is a perspective view of our complete invention, showing the same in operative position. Fig. 2 is a central, vertical sectional view of our invention.

'Fig. 3 is a bottom plan view of the heater shell with the central steam pipe in section, and viewing the same on the line indicated by the arrow 3. Fig. 4 is a top plan view of the base 6, showing'the pipe 29' in section; the view being taken on the plane in dicated by the dotted line marked with the arrow and the numeral 4 in Fig. 2. Fig. 5 is a cross-sectional view offthe base taken on the line 55 of Fig. 4.

In the construction of our invention we provide a base 6 provided with 'a water inlet port 7, a steam port 8 and a hot water outlet.

port 9. In the ports 7 and 8 are inserted pipes 10 and'l l; the pipe 10 is connected to a valve 12 WlllCh is connected to the water main 13 and by said valve and through the operation of the valve stem 14, the supply 0 water from the water main is regulated. The piipe 11 is connected to a similar ;valve 15 an is governed by the valve stem 16 which regu ates the inflow of live steam admitted through the'pipe 17. In the,port 9 is placed the hot water supply pipe 18 through which the heated water is rmitted to flow into any suitablereceptac e 19.

Upon the base 6 is mounted the heater 20 which consists of an outer shell 21, an inner cylindrical wall 22 which is formed integral with the outer shell 21 by means of the spurs 23, forming between said outer shell and cylindrical wall a water. receptacle or pas- Speclfication of Letters Patent.

sage 24. The outershell is provided at its 0 top and bottom with a projecting flange 25 having suitable perforations 26 by which the same can be securely bolted to the base 6 and the hood 27 Between the heater and the'base and hood is located a strip of packing material 28 arranged to make an absolutely water-tight joint. The water port 7 in the base is so arranged as to communicate with the water receptacle or passage 24 (see Fig. 2),-so as to admit the water from the water main to pass upwardly and fill the entire chamber between the outer shell 21 and cylindrical wall 22.

In the port 8 of the base is screw-seated :1.

its top with a plurality of perforations 30 through whichthe live: steam passing from the pipe 11 is permitted to jet through into thewater passage 31 located between the central steam pipe 29 which is provided near pipe 29 and the inner surface of the cylin- 8&0

drical wall 22. Water is permitted to pass into this chamber by passing over-the top of the cylindrical wall by over-flow, and as this water is passing downwardly. the jets of steam passing through the perforations 30 $5 come in direct contact with the sheet of water, heating the same, and this water is permitted to pass out of said chamber through the port 9 which has direct communication with the chamber. I

In the ipe 29 is seated the valve 32 which is of suEcient length to cover the entire series of perforations 30 when manipulated by the valve stem 33, the valve 32 is screwthreaded in the pipe 29, and leakage between the valve stem and hood is prevented by the stufiing box 34. Said stem is provided with a valve handle 35 by which the same maybe readily operated. By means ofthe valve 32 the supply of steam can be regulated and this is accomplished by operatm the valve so as to open or close any num er of the perforations in the pipe. The inflow of the steam can also be re lated by means of the valve 15. This fi pends upon the de cc of heat of the steam and'the amount 0 heat required for heating the water supply.

In operating our invention we deem it best to first turn on the water supply, then I the pipe 29 out through the perforations 30,

the steam then coming in contact with the water and in this manner supplying the receptacle with 'water of the desired degree tion,

of heat.

The circulation of the water and steam is clearly indicated in Fig. 2 by the arrows.

Having thus fully described our invenwhatwe claim as new anddesire to have secured to usfby the grant of Letters Patent, is:

1. A device of the class described comprisin a heater composed of an outer shell rovi ed with a lurality of water circuating passages; a ase provided with a plu-r. ralit'y of ports; a steam supply pipe located in the heaterand communicating with one of thegports in the base, the remaining ports of said base communicating with the respective water passages of the heater; a valvelocated in the steam pipe for regulating: the supply of steam to contact with the water whilein circulation, substantially as described. k V 2. A device of the class described comprising a'heater composed of an outer shell; an innercylindrical wall; a central perforated steam pipe; a base provided with a plurality ofv ports, each port: registering with itsyrespective compartment of the heater; a valve located in the steam pipe for regulating the supply of steam to pass :through. the perforations to contact with the waterwhile in circulation, substantially .;-.-3.' A device of the class described comprising a heater composed of an outer shell an inner cylindrical wall located therein; a base supporting said shell and wall; a

Water inlet formed in said base and commti nicating with the space between the ,outer shell and cylindrical wall; a steam port 10- rated in said base andterminating centrally in the, heater; a perforated steam pipe screw-seated in said ort and extending centrally into the cylin rical wall; a discharge port located in the base and communicating with the space between the steam pipe and cylindrical wall; and a valve located in the steam pipe for regulating the passage of steam from the steam pipe into the water compartment, substantially as described.

4. A device of the class described comprising a heater composed of an outer shell; an inner cylinder spaced from the outer shell by spurs forming a water passage between the outer shell and cylinder; a steam pipe located within the cylinder; a base provided with a plurality of ports, the center port communlcating with the steam pipe and in which the steam pipe is fastened, the remaining ports communicatin with the water passages through one 0 which the water is admitted between the outer shell and cylinder, the other port permitting the discharge of the heated water from the passage between the inner shell and the steam pipe, said steam pipe being provided near its upper end with a plurallty of jets and a valve 'screw seated in the steam pipe for regulatin the discharge of the steam through t e ports to contact with the volume of water passing from the outer passage over the top of the cylinder through-the passage formed by the inner cylinder and steam pipe, substantially as s ecified,
